PL3307 Decoder Integration Guide
Imager Preferences
The parameters in this chapter control image capture characteristics. Image capture occurs in all modes of
operation, including decode and snapshot.
Operational Modes
The decoder has two modes of operation:
•
Decode Mode
•
Snapshot Mode
•
Snapshot with Viewfinder Mode.
Decode Mode
By default, upon a trigger event, the decoder attempts to locate and decode bar codes within its field of view.
The decoder remains in this mode as long as the trigger is active, until it decodes a bar code, or it reaches the
Decode Session Timeout on page 4-19
.
Snapshot Mode
Use Snapshot Mode to capture a high-quality image and transmit it to the host. To temporarily enter this mode
scan the
Snapshot Mode
bar code. While in this mode the decoder blinks the green LED at 1-second intervals
to indicate it is not in standard operating (decode) mode.
In Snapshot Mode, the decoder turns on the imager engine’s aiming pattern to highlight the area to capture in
the image. The next trigger event instructs the decoder to capture a high quality image and transmit it to the
host. A short time may pass (less than 2 seconds) between trigger activation and image capture as the
decoder adjusts to the lighting conditions. Hold the decoder steady until image capture, denoted by a single
beep.
If a trigger event does not occur within the Snapshot Mode Timeout period, the decoder returns to Decode
Mode. Use
Snapshot Mode Timeout on page 5-14
to adjust this timeout period. The default timeout period is
30 seconds.
To disable the aiming pattern during Snapshot Mode, see
Snapshot Aiming Pattern on page 5-14
.
Use
Video View Finder on page 5-26
to enable
Snapshot with Viewfinder Mode
. In this mode the decoder
behaves as a video camera until the trigger activates, at which time a Snapshot occurs as described above.
